Abstract

The present invention provides a liquid crystalline resin composition for a camera module, which is used for producing a component for a camera module whose surface is less fluffy, has high mechanical strength, does not easily generate blisters, has high dimensional stability, and suppresses warpage and deformation. The solution is to prepare a resin composition containing: (A) liquid crystalline resin; (B) platelet filler; and (C) copolymer selected from (C1) olefin-based copolymer and (C2 ) at least one kind of styrene-based copolymer, the content of (A) component is 64 to 78 mass%, the content of (B) component is 20 to 30 mass%, and the content of (C) component is 2 to 6 mass%, (B) The average particle diameter of a component is 20-50 micrometers, (C1) component and (C2) component consist of a specific component.

Description

technical field [0001] The present invention relates to a liquid crystalline resin composition for camera modules. Background technique [0002] Liquid crystalline resins represented by liquid crystalline polyester resins are widely used as high-functional engineering plastics because they have excellent mechanical strength, heat resistance, chemical resistance, electrical properties, etc. in a good balance. Recently, liquid crystalline resins are used for precision instrument parts by making use of these characteristics. [0003] In the case of precision instruments, especially optical instruments with lenses or the like, slight rubbish, dust, etc. can also affect the performance of the instrument. For example, in a component used in an optical device such as a camera module, when minute dirt, oil, or dust adheres to the lens, the optical characteristics of the camera module significantly deteriorate. In order to prevent such a decrease in optical characteristics, parts c...
